I have really enjoyed this particular game.  Yes, it is quite different from all the other genres but that is what makes this game unique.  The first thing that caught my attention was the music.  As you progress through the game the music really puts you in the thick of the battle.  Making you notice your surroundings and correctly pressing the action icons at the right moment.  The only challenged I received during play was playing Asura's Wrath on "HARD" and waiting for the "True Ending".  I know most people may not like this style of genre but it is worth the experience.  Give it a shot and enjoy!
